hi, the other day me and my friends make some dinner at house, it was the night before i ride, so one of them is a weight lifter and uses some powders like the "mega Mass" i think its a protein milkshake and stuff like those supplements etc. so the point is that the next day i went trainning and felt good, a little better than the other days so what im asking is if i can use those things the night before a race im having on a week... its an endurance race of 100 kms, and i think im ready for it but if i can make it better it would be ok. I'm asking this because i have read some advices that say its dangerous to use stuff like red bull and so if you're not used to them. tnks

so what im asking is if i can use those things the night before a race im having on a week...

You can eat just about anything the night before a race, as long as your system can tolerate it. I wouldn't experiment with anything radically different than what you're used to -- an unscheduled bathroom break during a race is not very convenient.

I prefer something simple and easily digested, like chicken with pasta or rice.
